Does the intervention order name the kids?
And yes, police do hand IOs out like lollipops. I believe, but can't confirm, police constables are admonished by their sergeant if they don't hand them out. I'll to do with butt covering in case you have very violent reaction one day and take it out on the family. Drop down to your local community legal centre with your paperwork and see if they can offer any suggestions. If the kids are named I don't like your chances.
Whatever you do, don't contravene the IO. If there are family law matters before the courts, then you need to play it carefully and legal advice may help you work out what to do when the IO gets to court (ie contest, consent without admission, give an undertaking, admit to acts). A lawyer at a CLC can advise the options in more detail and the effect on family law matters like parenting.
